Xna 3d Hexagon tile lag?

Sat, 10 Mar 2012 19:59:08 GMT

Hall�j,

jeg har lavet et br�t best�ende af 3d hexagoner lavet i Maya3D og lagt dem i en liste.

Derefter "Draw"er jeg modellerne p� sk�rmen, men hvis der er for mange, omkring 50*50, s� lagger det n�r jeg flytter kameraet.

Jeg forst�r det simpelthen ikke, er det fordi XNA accelererer p� software og ikke p� hardware, og i s� fald, hvad g�r jeg?
